SPECIFICATION forming part of Letters Patent No. 347,364, dated August 17, 1886. Application mea June 18,1885. semina 159,113. (No model.)

To all whom, t may concern: V

Be it known that I, ROBERT MIEHLE, a citizen of the United States, and a resident of the city of `Chicago, in theV county of Cook and State of Illinois, have invented certain new and useful Improvements in Inking Apparatus for Printing-Machines, of which the following .is

. a specification, towit:

This invention relates to the inking appa` ratus ofprinting-pres'ses, wherein thebed which contains theI form isreciprocated.

Theinventiou consists in the combination, with the bed and ink-table and theA'arrange-` ment hereinafter described, of the rollers which distribute the ink upon the ink-table receiving a continuous motion synchronous with the full backward and forward movement of the bed.

It `furthermore consists in other combinations of arrangements of parts,hereinafter fully described and claimed.

In the drawings, Figure 1 is a side vievr showing the gearing for operating theinkingrollers and their respective positions of the present improvement. Fig. 2 is a transverse vertical section of the same, showing the roll ers for'distributing the ink upon the ink-table, also theposition of the rack for imparting motion to the inkingrollers. Fig. 3 is a sectional end view of the form-rollers and distributingrollers which are `mounted above the same. Fig. 4 is a sectional end view similar to Fig. 3, showing the bearings of the form-rollers and` distributing-rollers with the line of section between the gearing and roller-frame.4 Fig. 5 is a plan view showing the .ends of the rollers in their respective positions in relation with the roller-frame. Fig. 6 is a longitudinal view showing one of the ridingfrollers with its central portion broken out to reduce its length, with the frame and bearings in section. Fig. 7 is aside view showing theinelined wedge in its proper position upon the frame for adjusting the form-rollers. Fig.' 8 is an end view of the same. Fig.`9 is a side view showing the diil'erent positions of the form-rollersupon the inclined wedge when of different sizes. Fig. 10 is a top planview of the inclined wedge. The description of the parts which make up the several combinations of the arrangement herein claimed isas follows:

i A designates the'press-frame. This may be 1 of any desired form. E is the cylinder in its usual position; B, the form-bed, which is reciprocated when in operation.

Upon the under side of the bed B are hangers K', having a rack, K, secured thereon, in which engages a pinion, T', upon the inner end of shaft T, the same being journaled into the press-frame A, as shown in Fig. 2, its Outerl endbeing provided with a gear, T2, for communicatingmotion to gear T3, which en gages gear T. 4 This gear in tu rn imparts motion to theriding (or distributing) rollers e203 by meshing with gears T5 T6 upon their outer ends, as shown in Fig. 1. These rollers have connections with the form-rollers c c c and distributing-roller 0*, as follows:

The rider c?, as shown in Figs. 1, 3, and 4:,is placed above and engages the form-roller c nearest the cylinder and center form-roller c, so as to impart a turning movement to both. The other roller, c, is slightly raised and engages the outer form-roller c, as clearly indi cated in Fig. 8, the distributingroller c4 serving to make connection between the ridingrollers c'l and c3, so that the ink will be distributed' equally upon all'the rollers after the form-rollers c c c have rolled upon the inktable I. Y p

The side vibrating movement for the ridingrollers c2 c3 is obtained by means of the cam .I upon shaft J', which imparts an oscillatory movement to the vertical shaft g3 through the medium of rook-lever g, the stud j thereon engaging into groove of cam J, as shown in dotted lines in Figs. 1 and 2, the link g making a connection between the lever g and crankarm g2 upon the lower end of shaft g3. The same is provided with a cross-lever, g, upon its upper end, having studs it', which engage the grooved collars g5 gnpon the outer ends of roller c2 c3, as shown in Fig. 1. The groove of cam J is such that it will withone revolution rock the lever g, so as to impart one oscillatory movement to the vertical shaft gr3 while The following is a description of the rollers which distribute the inl; upon the ink-table and the mechanism by which they receive their sidelong vibratory movement: I designates the ink-table, which is mounted upon the forward end of the bed B, its upper surface being fiush with (or a trifle higher than) the type (or printing) surface, and in the frames C are mounted rollers a a, which lie parallel with the ink-table I,(or the line of movement thereof,) their position being such that the inner roller a toward the cylinder E will pass over the ink-table I as much as to just clear the printingsurface when the bed B has received its extreme forward movement. The duty of these rollers is to distribute the ink upon the ink-table when received from the transfer-roller x, which engages the fountainroller X, and the riding-roller 0"', which engages the distributing-roller a a, as shown in Fig. l.. The cam J,which is employed to impart the sidelong movement to the riders cl2 c", is also used to impart movement in like manner to the distributing-rol1ers a a by the extension upon rock-lever g, which engages the crank-arm f upon the lower end of the vertical shaft f, (this shaft is placed upon the inner side of the press-frame A,as shown clearly VVin Fig. 2,) the said shaft having upon its upper end a cross-lever, f, provided with studs f4, which engage the grooved collars fz upon the rollers a a, which, when the shaft f is oscillated, impart a sidelong movement to the same.

It will be seen by the above description that the sidelong movement of the rollers a a, and

the riding-rollers cz c3 are identical; but this movement may be somewhat varied from the above by forming the groove of cam J to impart any additional number of movements desired. It would then be necessary to provide a separate cam for the distributing-rollers a a, as one oscillatory movement of the vertical shaft g is sufficient for vibrating the rollers c2 c.

The continuous motion of the rollers a a, with the movement of the bed B, as mentioned in the first part of the specification, is obtained by means of the riding-roller (or cylinder) c5, which has a position above the rollers a a, so as to engage and impart a turning movement to the same, the rollerc receiving its movement from the shaft Y bythe bevel-gear Y4 upon the outer end of roller c", which meshes with the bevel-gearlv3 upon the upper end of shaft Y, as shown in Figs. l and 2. This shaft is set somewhat at an angle from a horizontal line, to connect with and receive a turning movement from the shaft T by the bevel-gear Y upon the lower end of shaft Y, meshing with bevel-gear Y2 upon the outer end of shaft T, the same receiving movement by engaging rack ,K upon the bed B with pinion T, which is secured upon its inner end. In practice the gearing between the roller c5 and rack K should be proportioned to communicate a motion to the rollers a a, which will be synehronous with the movement of the bed.

It is evident that a belt or chain may be used instead of the shaft Y and bevel-gearing between shaft T and roller c", if it be desirous to modify the above arrangement, and not depart from the spirit of theinvention. In some cases a side vibratory movement may be given to the roller In such eases the bevel-gear Y4 would be fitted with a key-seat, (or slot,) so as to slide endwise upon a spline placed upon the roller c5. The gear Y* would then be housed in at either side, to keep it in its proper position with the bevel-gear Y,

In order to describe the means by which the riding-rollers c?, c, and c5 are held in their respective positions, I will describe the arrange ment of but one, as the same arrangement is used for all three riding-rollers. Upon each end of the roller (or the stocks thereof) is a sleeve, (or bush,) c, which is fitted into slots c2 of the roller-frame C. The same are held in place by the pins c, as shown in Figs. 4- and 6.

To allow the riding-rollcr being easily removed, one of the pins e is provided with a screwtluead,which, when the roller is to be removed, allows the pin to be readily taken out and again replaced when the roller is put back.

Then the roller-gearing which communicates motion to the inking-rollers is placed at the inner side of the frame C, both the pins e3 of each distributing-roller may be made removable, and also the vertical pin n may be placed at each end of said rollers, and the attendant may then raise either side, as the dis. tributing-rollers are not always removed from the press when it is necessary to remove the form-rollers c. In such cases one end of the distributing-roller may be raised and placed upon the usual bracket provided therefor, the screw serving to keep the pin from working out when properly fastened. Still it is not necessary that the one pin e should be provided with a screw-thread, as it may be provided with a spring-catch, which would serve as well, and could then be more easily ree moved.

Vhen the form-rollers c c c and the rollers a a are to be removed, the thumb-screws e are withdrawn. from the frame C, and one end of the riders raised out from the slots ci. The other ends may be then withdrawn from the oppo site sleeve, which is secured into the frame C. The rollers c c c and a a may then be lifted out, as the sockets c in which they are held are open at the top, this operation being reversed when the rollers are replaced, and to allow the riding rollers c?, c, and to be moved in any direction. Then one end is raised, there is provided an extra joint upon one end by the pin a, formed upon the under side of the slot e2, or that portion ofthe frame C which forms thesame. The same passes down through the frame C, and is held in place by the nut n', as shown in Fig. 6 and in the dot- .IOO

` sleeves e from binding while withdrawing the rollers or replacing them. l

The sockcts,( or bearings) o', for the rollers c c c and rollers a care formed with two elongated slots, e, and are held in place by the-bolts e5,

which pass th rough the slots e and also through frame C. When the nuts el are drawn up tight against the frame C, the flanges esupon the bolts e5 serve to clamp the sockets c rmly in place. Y

To adj ust the form-rollers o c c properly with the riding-rollers c2 c3 and the printing-surface which they roll upon, there is provided an inclined wedge, G,which is'held upon the frame- 'C by the screw g, and has aposition just below the outer portion of the stocks (or journals) of each of the rollers c c c, which extend outward from the sockets c', as shown in Figs. 7 and S. rlhe incline of the wedge is such that when any of the rollers c c c are pressed against the riding-roller they will also be adjusted automatically with the surface they are tov roll upon, which will be readily understood by referring to Fig. 9. In this figure the formroller is represented in three different sizes when being of a full size, medium, and asniall size, this being due to the fact that these rollers are made of composition which has a great tendency to shrink, and when such shrinkage*- lstated, serving to adjust the roller properly with the printing-surface with the same pressure as it has against the riding-roller; and to prevent the incline being worn off by the end of the rollerjournal, which, rests upon the sanne, the wedge G is provided with anelongated slot, q2, for the screw g, as shown in Fig. 10, so that the same may be drawn back after the roller has been adjusted, the spring q', as shown in Figs. 7, 8, and 9, serving to hold the wedge G in place while adjusting the roller or when disengaged fro'm the same.

The advantage the removable inclined wedge G, just described, has over the automatic device heretofore used for adjusting the rollers is, by being made independent and removable of the roller-socket, it always preserves the proper incline for adjusting the form-rollers c, regardless of the wear upon the socket 'and 6o journal thereof.'

' or nearly so, and three distributingrollers placed above the same,with but one of `the distributing-rollers having engagement with two ellisse. 3

form-rollers, and one of saidl distributing-roll'- ers being slightly raised, so as to engage buone form-roller,'the other one of the said dis tributing-rollers making a connection between all six rollers, substantially as described.

In a printing press, the combination, with the reciprocating Ytype-bed, ,ink -table, and a series of form-rollers which receive the ink from the ink-table to deposit the same upon the form, of the distributing-rollers a a, having a riding-roller above the same for imparting a continuous motion to said distributing-rollers by mechanism, substantially as described, whereby the said distributing-rollers will receive a turning movement, which is at all times the same as the back and forward movement of the said bed, the position of the said distributing-rollers being such that they will justpass over the ink-table, substantially as described. .l Y

3. In a printing-press, the combination, with the bed B, ink-table I, distributing-rollers ad, riding-roller o5, of the shafts Y and T, having bevel-gear connections,'and the shaft T, having a pinion engaging rack K, substantially as and for the purpose set forth.

In a printing-press, the combination of the frame C, roller c, distributing or riding roller having sleeves or journal-boxes e, and inserting-pins e3, one of which is provided with means, substantially as described, for securing it in the frame C, and the vert-ical jointpin n, formed upon the portion of the frame C in which the saidjournal-box is held, as and for the purpose set forth.

8. In a printing-press, the combination,with the frame C, distributing or riding roller, the form-roller c, and the socket and journal thereof, of the inclined wedge G, being removable so as' to be independent of the socket and journal of the said form-roller c after the same `has been adjusted, substantially as described.
